Hello Andre,

I think that there is no good way to use in_interrupt() in asm/string.h.
Circular dependencies.

I've been using some form of this patch since last May, posted here several
times. It moves the mmx style memcpy into lib.a (mmx.c). I lose some
inlining, but since k7 does branch prediction for call addresses, inline
functions are somewhat less of a win. Certainly the big speedup from mmx is
more than enough to pay for it.

Cheers,
Tom
